double
in Edition Clear Qur'an by Talal Itani / Al-Ahzaab (The Clans)

33:30O wives of the Prophet! Whoever of you commits a proven indecency, the punishment for her will be doubled. And that would be easy for God.

33:31But whoever of you remains obedient to God and His Messenger, and acts righteously, We will give her a double reward; and We have prepared for her a generous provision.

33:68Lord, give them double the punishment, and curse them with a great curse.”
